The apparent inability of Dinophysis to take up nitrate suggests the existence of incomplete nitrate-reducing and assimilatory pathways, in line with the paucity of nitrate transporter homologs in the D. acuminata reference transcriptome. Dinophysis acuta is a photosynthetic species with yellow chloroplasts (Dodge, 1982, Larsen and Moestrup, 1992). Dimorphic cells, one half resembling D. acuta and the other half resembling D. dens (the proposed gamete form), have occasionally been observed in this species ( Reguera et al., 1990 , Hansen, 1993 , Moita and Sampayo, 1993 ).

Abstract. In the Uranouchi Inlet, which has a commercial fishery of littleneck clam Ruditapes philippinarum, potentially toxigenic species of Dinophysis acuminata showed an annual occurrence except for the summer of 2000–2002.

Dinoflagellate species of Dinophysis are obligate mixotrophs that require light, nutrients, and prey for sustained growth. Information about their nitrogenous nutrient preferences and their uptake kinetics are scarce. This study aimed to determine the preferred nitrogen sources in cultures of D. acuminata and D. acuta strains from the Galician Rías Baixas (NW Spain) and to compare their 学名 : Dinophysis acuminata (Claparède & Lachmann,1859) 分類(和名): ミオゾア門 > 渦鞭毛虫亜門 > 渦鞭毛虫下門 > 渦鞭毛藻綱 > ディノフィシス目 > ディノフィシス科 > ディノフィシス属 Consequently, field studies of Dinophysis and nutrients have been rare. Here, the temporal dynamics of Dinophysis acuminata blooms, DSP toxins, and nutrients (nitrate, ammonium, phosphate, silicate, organic compounds) were examined over four years within two New York estuaries (Meetinghouse Creek and Northport Bay).

2010-06-10 · Dinophysis is exceptional among dinoflagellates, possessing plastids derived from cryptophyte algae. Although Dinophysis can be maintained in pure culture for several months, the genus is mixotrophic and needs to feed either to acquire plastids (a process known as kleptoplastidy) or obtain growth factors necessary for plastid maintenance.

1 ABSTRACT: The dinoflagellate genus Dinophysis includes several species that cause diarrhetic shellfish poisoning, none of which have yet been established in culture. We report on the maintenance of Dinophysis acuminata cultures that were established in December 2005 and also on its feeding mechanism, and growth rates when fed the ciliate prey Myrionecta rubra with and without the addition of About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators Dinophysis acuminata C1aparède et Lachmann and Dinophysis norvegica Ehrenberg (two toxic species responsible for diarrhoeic shellfish poisoning) from West Boothbay Harbor were both found to 2010-06-10 · Dinophysis is exceptional among dinoflagellates, possessing plastids derived from cryptophyte algae.
